What Unity Actually Is (Editor, Engine, Project)
See how the Editor, the runtime engine, and your project files divide responsibility before you write a line of code. Short card.
Learning paths
Unity Engine Foundations
GameObjects, components, scenes, hierarchy, and prefabs - the mental model every Unity project is built from, before you write a single system.
Ordered roadmap
Unity Engine Foundations
Read each step in order. The connector note explains why the next topic follows.
GameObjects and Components: Unity's Building Blocks
Compose behavior from small components instead of inheriting it, and see why that split shapes every Unity project.
Scenes and Hierarchy: Where Your Game Actually Lives
Read a scene as a saved GameObject tree, and see why hierarchy position controls more than you expect.
Transform and Space: Parent, Child, Local vs World
Separate local from world space before a parented object starts moving in ways you did not expect.
Prefabs: One Source, Many Instances
Separate the source prefab from its instances and overrides before scripting starts touching either one.
Define a component boundary
Give one invented runtime component one clear responsibility. Short card.
